BATHYMETRY SURVEYS

State-of-the-art bathymetry and seabed surveys are executed for clients in the oil, gas, marine construction, naval and ports authority industries including pre-dredge and post-dredge surveys, buoy mooring and channel surveys. Creating detailed bathymetric charts of drilling and construction locations is essential for the design of infrastructure and the carrying out of offshore operations. Using Side Scan Sonars, Sub-Bottom Profiles and Magnetometers, we can deliver quality data of the seabed surface and shallow subsurface that can be used to effectively used in engineering and project planning.Hydrographic solutions include tidal monitoring, current profiling, meteorological analysis, siltation studies, seabed classification

GEOPHYSICAL SURVEYS

Kench Survey undertakes geophysical surveys for pipeline route, cable route and drilling locations. Information on the sediment layers and soil stratigraphy within the seabed is acquired by using equipment with different penetration levels and energy outputs depending on client specifications and project requirements. Also, equipment can be deployed to identify debris, unconformities, salt diapers, stratigraphic faults, subsea channels, existing man made structures and other possible hazards to field development activities.

GEOTECHNICAL SURVEYS

Soil investigations are often required by clients in the oil, gas and construction industries to solve civil engineering and offshore construction problems as soil formation is considered in engineering designs. Kench Survey undertakes geotechnical investigations on soil types, soil classification, shear strength, porosity, permeability and engineering properties of soils to determine their strength and foundation properties. Equipment used include gravity corers, jumbo piston corers, drilling rigs, CPT and PCPT equipment.

RIG POSITIONING

Personnel, positioning & navigation equipment and advanced positioning software are available to position drilling rigs precisely on to new and existing drilling locations. In addition, tracking systems have been developed for the positioning of anchor handling tugs and other ancillary vessels. Kench Survey also provides assistance with the installation of platforms, jacket sections and templates in offshore hydrocarbon provinces. Surface and sub surface positioning data is integrated to generate graphics for clients to make informed drilling decisions.

CONSTRUCTION SUPPORT SERVICES

Positioning and Navigation of Construction barges needing anchor monitoring, pipeline layback positioning and Mattress installation support. Carrying out Pre-routes and As-Laid services are also critical criteria for a successful pipeline and subsea infrastructure campaign.

DEBRIS CLEARANCE SURVEYS

Using subsea scanning sonar equipment and positioning to detect seabed surface debris and possible prior spud-can penetration sites can reduce the risk of damage to Jack-up MODU legs. This can save expensive time in problems with positioning these Jack-ups next to existing platforms and installations.
